Study of the Avifauna of Lake Erie Islands. 151 



FaJco sparvcrlKs simrveriiis. — Sparrow Hawk. 



Contrary to our expectations, we did not find this little hawk 

 at all common at any time. The largest number seen at any time 

 was four on September 5, 1910. It seemed to prefer the cedars, 

 and could occasionally be flushed from there. One sometimes ven- 

 tured down to near the end of the sand spit, but soon returned 

 and disappeared in the cedars. . 

 Pandion halitrtus carolinensis. — Osprey. 



• One was flying over Saw Mill Point August 8, 1910, another in 

 the vicinity of camp August 22, and another flying over the sand 

 spit September 5, 1910. There was no evidence of a nest any- 

 w'here on the island. 

 Asio flammeits. — Short-eared Owl. 



A single bird visited the cedax's in the vicinity of camp on A\i- 

 gust 11, 12, 23 and 27. Each time it was started from the ground 

 or near it from one of the depressions between the ridges. 

 Otus asio asio. — Screech Owl. 



Found on each visit, which included at least one night. It was 

 present all summer, 1910, and could be heard quavering any night. 

 It was difficult to find among the dense cedar growths, but we did 

 success in finding individuals occasionally. It is likely that this 

 owl is well distributed over the island in the woods. 

 Bul)o virginianus virginianus. — Great Horned Owl. 



One was discovered in the dense woods north of the point, and 

 west of the swamp on August 25, 1910. There were plenty of 

 suitable nesting places for this big owl. 

 Coccijzus americanus americanus. — Yellow-billed Cuckoo. 



Common in the vicinity of the swamp during the entire study 

 in 1910. Nests were not found in any numbers, but the birds were 

 giving their characteristic calls all day long. One nest was dis- 

 covered about fifty feet from the ground on the lirpb of an elm, 

 near the swamp. Individuals occasionally wandered well toward 

 the point among the cedars, but they clearly preferred the decid- 

 uous trees near the swamp. 

 Cocciizus erythrophthalmus. — Black-billed Cuckoo. 



Noted less than twenty times during the 1910 study. The dif- 

 ference in the calls of the two cuckoos had been questioned, so 

 particular attention was given to this study. In every instance 

 where the bird could be both seen and heard the phrased call of 

 this species was given, which distinguishes it from the preceding. 

 No nests were found, but there was clear evidence that these cuckoos 

 do nest on Pelee Island in limited numbers. There was no migra- 

 tory movement of either of the cuckoos detected. One would sup- 

 pose that their migrations would begin with the first chilly weather, 

 but such did not appear to be the case.
